Covariant functors commuting with direct limits

Category Theory 2023-11-16 v5 Representation Theory

Abstract

In this work we state conditions on a covariant right exact functor so that it commutes with direct limits. These conditions are related to the commutativity of the functor under direct limits of projective modules. We prove that if the functor commutes with direct limits of projective modules, then the functor commutes with direct limits.
